ABSTRACT
Objectives: To detect the diagnostic accuracy of rapid antibody detection test using IgM immunochromatography for scrub typhus in children. Methods: This cross-sectional study enrolled children aged 2 months-18 years hospitalized over a period of 18 months with undifferentiated fever of duration five days or more. The blood samples were subjected to serological tests like Weil-Felix, Scrub IgM ELISA, immunofluroscence assay (IFA) and rapid diagnostic test (IgM Immunochromatography). Diagnostic accuracy was measured against IFA as the gold standard. Results: A total of 90 children were included in the study, among which 43 children were positive for gold standard test IFA. Rapid diagnostic test showed sensitivity of 88.3%, specificity of 89.3%, positive predictive value of 88.3% and negative predictive value of 89.3%. The sensitivity, specificity, PPV and NPV of Weil-Felix test was 39.5%, 84.2%, 58.6 and 71.1%, respectively and of IgM ELISA was 93%, 89.3%,88.8% and 93.3%, respectively. Conclusion: IgM immunochromatography had good diagnostic accuracy for scrub typhus in children with acute undifferentiated fever.
ABSTRACT
Purpose: The study was conducted to compare the compliance to intravitreal injection treatment and follow?up in patients with center?involving diabetic macular edema (CI?DME) and treatment outcomes between a tertiary eye care facility and a tertiary diabetes care center. Methods: A retrospective review was conducted on treatment naïve DME patients who had received intravitreal anti?vascular endothelial growth factor (anti?VEGF) injections in 2019. Participants were people with type 2 diabetes who were under regular care at the eye care center or the diabetes care center in Chennai. The outcome measures were noted at months 1, 2, 3, 6, and 12. Results: A review of 136 patients treated for CI?DME (72 from the eye care center and 64 from a diabetes care center) was carried out. The severity of diabetic retinopathy (DR) was similar in both centers. There was no statistically significant (P > 0.05) difference in the choice of initial intravitreal drug in the two centers. At 12?month follow?up, only 29.16% came for a follow?up in the eye center vs. 76.56% in a diabetes care center (P = 0.000). The multivariate logistic regression showed increasing age was associated with non?compliance in both the groups (eye care center: odds ratio [OR] 0.91; 95% confidence interval [CI] 0.82–1.21; P = 0.044) and diabetes care center (OR 1.15; 95% CI 1.02–1.29; P = 0.020). Conclusion: The follow?up rate between eye care and diabetic care center with DME showed a significant disparity. By providing comprehensive diabetes care for all complications under one roof, compliance with follow?up can be improved in people with DME

ABSTRACT
Education is an intentionally trained activity focusing at nurturing the harmonious progress of an individual as productive, promising and reasonable individual in the society . A person needs set of skills to deal productively with life situations. Such skills are called life skills which help the person to deal effectively with any condition to get the desired outcomes. The present investigation was designed as a descriptive study and normative survey was the method adopted for the study. Stratified sampling technique has been used to select samples of 60 secondary school students. Problem solving inventory, decision making inventory and inter personal relationship questionnaire were the tools used. The data were analyzed through destructive measures of statistics mainly Mean and Standard Deviation and product moment correlation. From the findings, it can be concluded that there is no significant correlation between problem solving skill and interpersonal relationship, decision making and interpersonal relationship of secondary school students.
ABSTRACT
Purpose: To evaluate the effect of deep thermal punctal cautery in eyes with post?conjunctivitis cicatrization. Methods: This retrospective study consisted of patients who underwent deep thermal punctal cautery for post?conjunctivitis dry eye (PCDE). The diagnosis was based on a history suggestive of viral conjunctivitis in past followed by the onset of present clinical features of aqueous deficiency dry eye (ATD). All patients underwent a rheumatological evaluation to rule out underlying systemic collagen vascular disease as a cause for dry eye. The extent of cicatricial changes was noted. Best?corrected visual acuity (BCVA), Schirmer’s test, and fluorescein staining score (FSS; total score of 9) were analyzed pre? and post?cautery. Results: Out of 65 patients (117 eyes), 42 were males. The mean age at presentation was 25.769 ± 12.03 years. Thirteen patients presented with unilateral dry eye. Pre?cautery BCVA (logarithm of the minimum angle of resolution [logMAR]) and Schirmer’s test (mm) improved from 0.5251 ± 0.662 to 0.372 ± 0.595 (P value = 0.000, 95% confidence interval [CI]: 0.09–0.22), and 1.952 ± 2.763 to 4.929 ± 4.338 (P value = 0.000, 95% CI: ?3.79–?2.17); post?cautery, respectively. The pre?cautery FSS of 5.9 ± 2.82 reduced to 1.58 ± 2.38 (P value = 0.000, 95% CI: 3.46–5.17) post?cautery. The mean follow?up was 11.22 ± 13.32 months. No progression in cicatricial changes was noted in any eye during the follow?up. Re?canalization rate was 10.64%, and repeat cautery was performed with successful closure of puncta. Conclusion: Symptoms and clinical signs of ATD in PCDE patients improve with punctal cautery
ABSTRACT
Dry Eye Module (DEM), a software application, was developed to facilitate the streamlining of dry eye evaluation and documentation, to unify diagnostic jargon, and to analyze data input to generate a dry eye diagnostic report. This diagnostic report generated is based on the current understanding of dry eye diagnostic algorithms (Dry Eye Workshop 2 [DEWS2]/Asia Dry Eye Society [ADES]). Apart from its plausible role in aiding unprecedented multicentric dry eye demographic data collection, the application software can generate a customized referral letter to the rheumatologist, highlighting the salient ophthalmic features to be shared. DEM uses schematic illustrations to depict eyelid, conjunctival, and corneal parameters that impact the ocular surface in dry eyes that can be captured and compared during serial visits. Furthermore, DEM displays a symptom sign trend chart that graphically represents improvement/stability or worsening of the subjective and objective dry eye status. DEM can generate a curated prescription using preloaded advice templates. DEM includes facility for state-of-the-art advanced dry eye diagnostic reporting for super specialty use. The addition of DEM to the dry eye diagnostic armamentarium would help bridge the current unmet needs of dry eye evaluation. These are lack of uniform reporting, lack of multicentric data on a unified platform, the inability to ensure complete evaluation, inability to avoid lacunae during follow-up visits, and the lack of a simple patient-ophthalmologist and an ophthalmologist–rheumatologist interface.
ABSTRACT
An enhanced online and manual grading system, based on the I’s and E’s, for acute ocular chemical injuries is being proposed. E-PIX is designed to be an online/manual grading system that includes all the parameters that adversely affect the outcome of acute chemical injuries. The importance of addressing the I’s and E’s in chemical burns cannot be underestimated. These include the need for the documentation and management of epithelial defect (E), intraocular pressure (P) (IOP), ischemia (scleral) (I), and exposure (X) (acronym - E-PIX). Epithelial defect includes that involving the limbus (L), along with conjunctival (C), corneal (K), and tarsal (T). These additional parameters are graded and represented as an annotation along with the limbal grade providing a comprehensive grading for the injury. A manual entry sheet and a freely accessible online grade generator are a part of the system. The proposed enhanced grading offers a final annotation that provides a clear understanding of all factors that can lead to vision-threatening complications ensuring their assessment and hence subsequently their addressal to improve outcomes, if abnormal. The prognostication continues to be based on the grade of limbal involvement. The additional annotations impact prognosis and outcome if not addressed. Including the laterality of injury provides, in addition, a futuristic understanding of available options. The grade generator retains the flexibility to be dynamic with changes reflecting upon the healing process in the acute stage. The proposed system aims to provide primary and tertiary caregivers alike with a uniform grading system.
ABSTRACT
Pain and swelling are among the most frequently encountered complaints in an orthopedics outpatient department (OPD) relatively less common in a pediatric OPD. A high level of suspicion is required to diagnose bone diseases. Common conditions such as rickets, septic arthritis, and tuberculosis must be ruled out. Treatment such as antibiotics, anti-inflammatory drugs, or steroids may mask an underlying serious condition in which if left untreated can cause significant morbidity and mortality to the person. Here, we discuss a case of a young infant 11 months of age who had symptoms suggestive of septic arthritis and was later found to have Brodie’s abscess which is a type of subacute osteomyelitis on further evaluation which is usually mistaken as a tumor. This age at presentation is rare.
ABSTRACT
Renal abscess is very rare among intra-abdominal abscesses in children. Ascending infection is the most common cause in children compared to hematogenous spread in adults and Escherichia coli is the main pathogen. Persisting high-grade fever is an alarming sign to intervene and has to be taken care of. Here, we are presenting the case of a 3-year-old boy with Klebsiella urinary tract infection and E. coli renal abscess of 4 cm size. Contrast-enhanced computed tomography abdomen helped in early intervention and management. The child responded very well to parenteral antibiotics and ultrasound-guided percutaneous aspiration.
ABSTRACT
Background: Trinidad and Tobago ranks number 45 in the world for total deaths due to coronary heart disease. Predictive tests for coronary angiographic results set the basis for earlier monitoring of the disease before additional complications become obvious. Aims and Methods?This study aimed to evaluate the anthropometric and biochemical parameters of 124 patients with suspected coronary artery disease (CAD) in Trinidad and how these parameters correlate to the findings at angiography. Results?The biochemical parameters showed statistically significant correlations with CAD severity by Spearman's rank-order correlation. Two clinical parameters showed significant associations with CAD severity—ethnicity (?2 (4)?=?12.925, p?=?0.012) and presence of type 2 diabetes at baseline (?2 (4)?=?21.483, p?<?0.001). Conclusion?Biochemical parameters such as fasting blood sugar, N-terminal pro B-type natriuretic peptide, creatinine, and hemoglobin A1c were well correlated and well associated with the severity of CAD after diagnosis by the process of coronary angiography. Hence, these factors can be taken into consideration to predict the severity of CAD.
ABSTRACT
Background & objectives: The National Tuberculosis (TB) Control Programme has transitioned from thrice-weekly to daily drug treatment regimens in India. This preliminary study was conceived to compare the pharmacokinetics of rifampicin (RMP), isoniazid (INH) and pyrazinamide (PZA) in TB patients being treated with daily and thrice weekly anti-TB treatment (ATT). Methods: This prospective observational study was undertaken in 49 newly diagnosed adult TB patients receiving either daily ATT (n=22) or thrice-weekly ATT (n=27). Plasma RMP, INH and PZA were estimated by high-performance liquid chromatography. Results: The peak concentration (Cmax) of RMP was significantly higher (RMP: 8.5 ?g/ml vs. 5.5 ?g/ml; P=0.003) and Cmax of INH was significantly lower (INH: 4.8 ?g/ml vs. 10.9 ?g/ml; P<0.001) in case of daily dosing compared to thrice-weekly ATT. Cmax of drugs and doses was significantly correlated. A higher proportion of patients had subtherapeutic RMP Cmax (8.0 ?g/ml) during thrice-weekly compared to daily ATT (78% vs. 36%; P=0.004). Multiple linear regression analysis showed that Cmax of RMP was significantly influenced by the dosing rhythm, pulmonary TB and Cmax of INH and PZA by the mg/kg doses. Interpretation & conclusions: RMP concentrations were higher and INH concentrations were lower during daily ATT, suggesting that INH doses may need to be increased in case of a daily regimen. Larger studies are, however, required using higher INH doses when monitoring for adverse drug reactions and treatment outcomes.
ABSTRACT
Background: The purpose of the present study was to analyze the etiology, incidence, pattern, and treatment modalities of patients with maxillofacial fractures treated at the Department of Dentistry of a medical college in Pondicherry during the period between June 2011 and June 2019. Materials and Methods: A retrospective epidemiological study of 277 patients treated for maxillofacial fractures between June 2011 and June 2019 was performed. Data regarding age, gender, etiology, site of the fracture, time of injury, presence of associated injuries, treatment modalities, and complications were recorded. Results: A total of 491 maxillofacial fractures were seen in 277 patients. These were 261 males (94.2%) and 16 females (5.8%) with a male to female ratio of 16.3:1. Most of the patients 79.8% were in the age group of 11 to 40 years. Most common cause of injury was Road Traffic Collisions (RTCs; 62.1%), followed by fall (20.2%), assault (14.4%) and others (3.3%). Fractures of the mandible (52.3%) and zygomatic complex (18.9%) were the most common maxillofacial fractures reported in our study. 196 patients sustained associated injuries with a prevalence of soft tissue injury (61.2%). Majority of fractures were treated with open reduction and internal fixation (ORIF; 71.9%) of patients followed by closed reduction (17.7%) and observation only (10.4%). Postoperative complications were presented in 16.8% of the patients in the study. Conclusion: RTC is the commonest cause of maxillofacial injury with a male predominance in our study. Mandibular and zygomatic complex fractures were the most common. ORIF remains the preferred method of treatment.
ABSTRACT
Growing evidence suggests that polycystic ovarian syndrome (PCOS) and Bronchial asthma coexist thanks to their common pathogenicity route. Both PCOS and Bronchial asthma has been associated with chronic low grade inflammation which results in hormonal disparity. One such case of a young woman with a medical history of Bronchial asthma presented with complaints of irregular menstrual cycle with amenorrhea and episodes of asthmatic attack once a month. The laboratory investigations including both blood and sonographic studies revealed the elevated absolute eosinophilic count, serum IgE and bilateral polycystic ovarian cyst. The Patient has been treated with internal medications and was advised to continue the physical activity such as walk for once a day and Pranayama (breathing exercise) as an adjunct to the treatment. After the treatment period of about 10 months, the outcome was assessed by both clinical prognosis as well as with USG report. The case study is about managing PCOS as well as bronchial asthma by Siddha therapeutic intervention and efficacy of the chosen drugs towards the ailments has also been explained with the help of preclinical studies conducted on the individual herbs of the formulation included in the study. This study could help to explore the therapeutic potential of Siddha medicine towards alleviating the low grade inflammation and hormonal imbalances associated with both Bronchial asthma as well as PCOS.
ABSTRACT
Background: Sleep plays an important role in our life. Adolescents undergo several changes with puberty and have a preference for later bedtimes due to internet usage. Evidence shows that many adolescents are not ob-taining the required amounts of sleep (8-10 hours) due to inadequate sleep practices. The objectives of this research were tostudy sleep-pattern among adolescents in Semi urban Coimbatore and also to determine the sleep hygiene practices among the adolescents Methodology: This study is a school based cross-sectional study. A total of 300 adolescents from class VIII to XIIth were selected using simple random sampling. Data was collected from February to May 2018. A struc-tured questionnaire for sleep pattern and Sleep Hygiene Index was used. Results: The adolescents’ mean sleep duration was 7.49 ± 1.12 hours on weekdays and 9.32 ± 1.55 hours on weekends. Mean Sleep Pattern Index (SPI) score was 22.48±6.9 and Mean Sleep Hygiene Index (SHI) score was 17.51±6.3 in our study. Conclusions: Majority of the adolescents had moderate scores of sleep pattern and sleep hygiene practices. Interventions directed towards promoting good sleep hygiene strategies are required to improve the physical and emotional health of adolescents.
ABSTRACT
Introduction: Neoplasms that are derived from odontogenic tissues represent an uncommon and heterogenous group of enti- ties in oral and maxillofacial region comprising about 1% of all jaw tumors. Ameloblastoma received particular attention of oral pathologists due to its local aggressive behavior. Objective: Indian studies, regarding prevalence of ameloblastoma are very few. The present study was done to analyze and compare clinical, radiographic and histopathologic features of 57 cases of ameloblastomas in India retrospectively. Materials and methods: 57 cases of histologically diagnosed ameloblastomas were retrieved from the archives over a five year period to analyze the age, sex, site, clinical presentation, radiographic features and histopathology. Results: In the present study, ameloblastoma accounted for 77% of all odontogenic tumors with a mean age of 37.5 years in males and 42 years in females. About 60% of the cases revealed mandible as most common site predominantly of posterior re- gion with common clinical presentation as painless swelling. Radiographically, multilocular radiolucency was noticed in about 54.3% of cases. Among the histological variants of solid/multicystic ameloblastomas, follicular variant was reported to be the most common (38%) and intraluminal variant (19%) to be the common subtype in unicystic ameloblastomas. Statistical analy- sis was done among the histological variants of ameloblastomas which showed no statistical significance (p<0.05). Conclusion: The findings in the present study were well in accordance with previous reported studies. However, extensive studies with larger samples need to be carried out in the Indian population to evaluate the incidence of ameloblastoma for more definitive results.
ABSTRACT
The Siddha system of medicine is an ancient medical system, which provides ‘Holistic Health’. The word ‘Siddha’ originated from the word ‘Siddhi’ meaning achievement of perfection, eternal bliss and accomplishment. The Siddha system evolved based on ninety-six tools (96 Thattuvam) which include physical, physiological, psychological and intellectual aspects of every human being. Among the 96 tools, the five elements i.e. Pancha bootham namely Earth, Water, Fire, Air and Space are the fundamental units of everything in the human body and the cosmos. There are three vital life factors (Vaatham, Pittam, Kabham) responsible for good health. There is a relationship between these to maintain the body’s healthy. Any increase or decrease in humour causes diseases. Thirthoda sama porutkal (TSP) maintains these humour when we are using our regular diet. This article details the TSP to maintain the body healthy.

ABSTRACT
Introduction Proximal humeral fractures are now recognized as an increasingly common fracture, accounting for 4%–5% of all fractures and 45% of all humeral fractures [1,2]. It is the third most common fracture, in people above 65 years of age, after fractures of the hip and distal radius [3]. These fractures have a bimodal distribution occurring either in young people after high energy trauma or in those older than 50 years with low- velocity injuries like simple fall [3]. 85% of these fractures are minimally displaced and are effectively treated with immobilization followed by early motion. The remaining 15% of these are either displaced or unstable. These fare poorly with non-operative treatment and are better treated with surgical intervention. Surgical treatment is necessary especially in young patients and active elderly people in order to prevent minimal dislocations of tuberosity or articular surface from compromising the long-term articular function. This study was planned to evaluate the outcome of proximal humerus fractures managed with PHILOS plate after approval by the Institutional Ethical Board. To evaluate the ef?cacy of PHILOS plate in the treatment of Aims And Objectives proximal humeral fractures and assess its functional outcome. To assess any complications that could arise postoperatively Early rehabilitation of the patient Hospital Based Prospective study. Methods And Materials Study Design: Study Period: October 2019 to September 2022. Study is conducted in Department of Orthopaedics, Andhra Medical College, Study Setup: Visakhapatnam. Patients attending emergency/orthopaedic OP and admitted in department of Study Population: orthopaedics in King George Hospital, Visakhapatnam with proximal humerus fractures and are classi?ed according to Neer's Classi?cation 30 patients admitted in the Department of Orthopaedics, King George Hospital, Visakhapatnam Sample Size: with proximal humerus fractures in the above said period. We have included 30 proximal humeral fractures in our Results study. Males dominated and left side is more common than right. Domestic falls are common than road traf?c accidents. 2-part fractures are more common than 3- and 4-part fractures. All of them are treated with PHILOS stable angled plate. Complications like stiffness, screw penetration and super?cial infection occurred in our study which are dealt appropriately. Signi?cantly, we could prevent varus malunion which is notable in our study. Rehabilitation started early with pendulum exercises and could achieve good range of useful movements for most of the cases. Average range of radiological union is 13.5 weeks PHILOS plate, stable, angled construct is used in all our cases and the results evaluation done with . Conclusion Constant Murley score which ranged 54 to 87. Our average score is 67.43 which is in concurrence with few of the studies. The rehabilitation after operation started early with pendulum exercises as soon as the patients compliance within the limits of pain. The range of movements in our study, abduction maximum range obtained is 120 to 150 degrees and forward ?exion 90 to 120 degrees and rotations average score is 7. Though we have few complications like stiffness of shoulder (5), AVN (1), intra- articular screw penetration (1), super?cial infection (1) and subacromial impingement (1), we have dealt with all these complications appropriately. Signi?cantly, varus malunion did not occur in our study
ABSTRACT
Background & objectives: The National Monitoring Framework for the prevention and control of NCDs in India has set targets for reduction of risk factors relative to the measure recorded in 2010. Estimates for 2010 and 2015 were established using meta-analyses in the absence of a national risk factor survey till 2017. Methods: We searched national survey reports and also articles published in English from India between 2008 and 2017 in PubMed, Google Scholar and Cochrane review databases for specific risk factors among 18-69 yr Indians. Quality of studies was evaluated using Joanna-Briggs tool, but all studies were included in analyses. Estimates for each of the eight strata by age, gender and place of residence, respectively, were generated. MetaXL was used to calculate the pooled estimate for 2010 and 2015 using a random effects model. Strata-specific estimates were combined to arrive at national estimate using population weight of each stratum. The credibility of the estimates was determined using four parameters - average Briggs score; representativeness of the contributing studies and precision and stability of the estimates. Results: The estimates [95% confidence interval (CI)] for 2010 for different risk factors were as follows: current alcohol use, 15.7 per cent (13.2-18.2); current tobacco use, 27 per cent (21.4-32.6); household solid fuel use, 61.5 per cent (50.2-72.5); physical inactivity, 44.2 per cent (37.8-50.6); obesity, seven per cent (3.8-10.2) and raised blood pressure, 20.2 per cent (18.4-22.1). In 2015, compared to 2010, tobacco use showed a relative decline of 18 per cent, household solid fuel use of nine per cent and physical inactivity of 15 per cent. The estimates were stable for alcohol use, raised blood pressure and obesity between 2010 and 2015. All estimates varied between moderate and high degrees of credibility. Interpretation & conclusions: The estimates are consistent with other available estimates and with current national-level initiatives focused on tobacco control and improving access to clean fuel. These estimates can be used to monitor progress on non-communicable disease risk factor targets for India
ABSTRACT
Background & objectives: Bacillus subtilis subsp. subtilis (VCRC B471) and Pseudomonas fluorescens (B426) produce mosquitocidal biosurfactant, surfactin and di-rhamnolipid. The objective of the study was to carry out a small-scale field evaluation of the two biosurfactants to determine the efficacy, application dosage, residual activity and frequency of application against Anopheles stephensi immatures in selected sites in Goa, India. Methods: Surfactin (VCRC B471) and di-rhamnolipid (VCRC B426) were formulated as aqueous suspensions (5% AS), and were applied at the dosages of 34, 51 and 68 mL/m2 and 27, 41 and 54 mL/m2 respectively. Two experiments were carried out with the two formulations. Results: Surfactin (VCRC B471) formulation was effective at all the dosages and there was sustained reduction (>80%) in immature density in the treated sites up to 18 days in experiment 1 and up to 15 days in experiment 2. No pupae were found in the treated sites throughout the study. Di-rhamnolipid (VCRC B426) formulation was also found to reduce the immature density in the treated sites up to 14 days in experiment 1 and up to 15 days in experiment 2. Interpretation & conclusion: For VCRC B471, the optimum application dosage determined was 51 mL/m2 and for VCRC B426, 27mL/m2 . The formulations are to be applied fortnightly for effective control of Anopheles. The application dosage determined in the present study can be used for large scale field evaluation to assess their suitability for use in public health programmes for the control of Anopheles mosquitoes vectoring malaria
